To open my window on the bus

You definitely caught it on the bus you were barely on, and definitely not from a manky, germ ridden child that you've spent ages in a classroom with.
Bore off.... once again.... your health needs don't trump other peoples health needs.

Being able to ensure someone definitely doesn't get ill somewhere is fucking magic
Hospitals can't manage it and they have stringent infection control measures

From one immunocompromised person to another, OP you are genuinely fucking insane and I'm surprised your job lets you get away with half of what you claim. Open windows all day every day and not being able to be physically near your students ... come on now, that's absurd!! I have to say that you were my son's teacher I'd be pulling him out of your class. You are NOT cut out for working with children, get over yourself!!

Thst said most science has been considered witchcraft at some time in history. The world must be a confusing and exciting place for some people on this thread.

Ventilation isn't magic.

There's no virus in the classroom or corridors because her reasonable employers magic them away

They're only on buses which she didn't stay on for long as she got off and walked!

So you definitely didn't catch the virus from any of the children in any of the classes you teach then? No?

Viruses are only on buses and not in classrooms? 🤔

How irresponsible of you to have got off the bus to walk in the cold and rain because you’re causing arguments on a bus of all places! You are unreliable and should resign.

Possibly, if they were standing there for as long as people stay still on a bus an if doors didn't keep opening and closing at both ends.

I'm I was going to say surprised, but actually it's more that I'm depressed that people seem to have such difficulty grasping this.

Imagine it's not aerosols in the air but biting bugs in water. Do you think you would get bitten more sitting in a bathtub of the bug filled water for half an hour, or quickly crossing a stream with bugs being swept past you?

I think a school corridor with intermittent crowds of people talking or shouting sounds much more virusy than a bus

As I keep saying, the nature of aerosols means that if the air is relatively still (which it is at the back of the bus with no windows open. If it wasn't the people who say moving cold air makes them ill wouldn't be so horrified about windows being open, it would happen every time the doors open) the aerosols will accumulate. This means that anyone breathing that air in will pick up a large load of the virus that is hanging in the air.

Someone breathing them out in a corridor as they go from A to B will leave very little behind them, compared with someone sitting still on a bus for the duration of their journey, add to that the other people causing the air to move by moving through the corridor and it is a much lower risk environment.

The air on a bus changes more than the air in a corridor does 🤣

Buses stop every few minutes and open the doors, corridors (especially in a school) tend to be empty and then heavily full and then empty again, with no open air coming in

I prefer windows open but am not too fussed as try and keep bus journeys short as I start to feel a bit queezy after a while.

The problem with opening the window above your head is the person behind gets the draught in their face!

Again, from my post just up there ^

"If a bus has no open windows the only new air comes from the door, and as it has nowhere to go it doesn't move the air through, it will just swirl and do a small air exchange, hardly affecting the soupy air further back."

Lol a bus is ventilated too - the bloody door opens and people move around every two minutes.

as in my post above:

"If a room is ventilated (which a corridor generally is, due to doors opening and closing and people churning the air as they walk through, moving the air) and someone infected isn't in it for a long period (which they generally aren't in a corridor) it's relatively low risk."

people don't tend to sit in a corridor for a long period with all the doors and windows shut.

It's not really being near people (although the closer you are the more you're in the cloud of their exhaled breath), it's being in an unventilated space that someone has been breathing out aerosols into for a while. Turns it into virus soup.

Like a corridor full of people that have been walking through....

Being cold and wet I think just makes you tired, which yes can make you a little more susceptible. Walking you'd probably stay fairly warm, it's just not very enjoyable.

If being at work and travelling to and from work is dangerous for you, you must either find work that is safer for you eg working from home, or come to terms with the fact that the universe cannot or will not rearrange itself to accommodate your wishes. All the stress you are putting yourself through is not helping your immune system, which would rather that you were happier

What would you put that down to specifically?

Your consultant told you to get off the bus regardless of the weather conditions, darkness or heavy bags if you can’t have a window open?

If closed windows on buses are so harzardous to you why don’t you drive or learn?

Being cold and wet can compromise your immune system though and make it weaker which... gasp... makes it easier to get ill.

It's not close contact so much as breathing in the particles.

Unless you are climbing in and out all the open windows then you are walking down corridors other people have to use. If someone else happens to be in the corridor to you screech at them "GET OUT I'M THE ONLY PERSON ALLOWED TO USE THIS CORRIDOR FOR THE NEXT HALF AN HOUR"?

If no one else is changing class does that mean you leave your classroom before the end of class and leave your class sat there until the bell goes? Because otherwise they'll be moving around too...

People still come too close to you in the supermarket even if you're avoiding them. They breath on items you then pick up, viruses can also be transmitted via touch.
